Hiya Tiggernancy, I've got the XS frame as well I tried alot of the small frames and even though 44cm seems small it's just that lettle bit to big for me so I couldn't believe my luck when I plonked my butt down on the OCR 3..it fits like a glove. I didn't even bother changing the saddle as I found it really comfortable so all in all it's the perfect bike for me. Now may I shouldn't tell you this but do you know they do the TCR's in extra small too .
